Be it known that I, TnonAs JOSEPH MORI- ARTY, a citizen of the UnitedStates, residing at Newport,i n the county of Newport and State of RhodeIsland, have invented certain new and useful Improvements in Devices forLocating Sunken Articles; and I do declare the following to be a full,clear, and exact description of the invention, such as will enable oth-Io ers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which forrn a part of thisspeciiication.

This invention relates to new and useful improvements for locatingsunken articles; and it consists in the provision-oi a buoy which ishoused in a suitable receptacle and anchored to the article which issunken by means zo of a cord which has one end secured to the casing,the other end to the b'uoy, and wound about the latter, means beingprovided whereby said buoy may be released from its'casing, which iscarried by the sunken article, means being provided for automaticallyreleasing the cover of the casing by hydrostatic pressure while underwater in conjunction with clock mechanism, which may be set so as toallow retaining-bolts to be withdrawn at a 3o predetermined time.

More specifically the present invention consists in' the provision of adevice for indicat ing the location of slinken articles, such astorpedoes, firearms of various kinds, lobsterpots, fish-cars, die., andconsists in confining within a casing a buoy, about which is reeled acord, which cord is anchored to the casing, the latter being of suchsize as to be readily fitted into .the article the location of which 4ois to be indicated, said casing containing a clockwork which is designedto withdraw a retaining-bolt, and a spring-actuated piston which hasconnection with a second releasingbolt, whereby the pressure 'of waterupon the piston-head will cause the second bolt to withdraw from itsengaging relation with the cover of the'casing, whereby the buoy willbe'allowed to leave the casing and float to the surface o f the water,thus forming an indication 5o of the sunken article.

To these ends and to such others as the invention maypert-ain thesameconsists,furth`er, in the novel construction, arrangement, andadaptation of parts, as will be hereinafter more fullydescribed and thenspecifically dened in the appended claims. l

My invention is clearly illustrated inthe accompanying drawings, which,with the letters of reference marked thereon, form a part of thisapplication, and in which drawings 6o similar letters of referenceindicate like parts throughout the several views, in which- Figure l isa sectional view through the casing and the buoys and piston containedtherein. Fig. 2 is an end view of the casing, show- 65 ing the coverremoved. Fig. 3 is a sectional view through a portion of the stock of agun, allowing the device as applied to the stock.

' Reference now being had to the details of the drawings by letter, Adesignates the cas- 7o ing containing my improved mechanism, which maybe made of any suitable shape for the purpose for-which it may bedesigned, and in the present instance I have shown the casing ascylindrical andadapted to beiittcd 7 5 within an automobile torpedoY orany other article the location of which isdesired tobe determined whensunken. This casing con- Atain's the buoy B, about which is reeled arope C, one end of which is connected to the cas- 8o ing, as at C', andits other end to the buoy, as at C2. Said casing has a cover D, which ishinged at D to the casing and is provided with two catches D2 and DS,which are engaged by the spring-actuated bolts E and F. The bolt E has aseries of rack-teeth E at one end, which teeth are designed to mesh withthe teeth g of the pinion-wheel G, which is mounted on the shaft G' ofthe clockwork mechanism, which is contained within the 9o compartment 1Iof the casing. This clcckwork mechanism is ot' the ordinaryconstruct-ion common in alarm mechanisms and so arranged that-'it may beset to go olli at any 'stated time and cause the bolt E to be disen- 95gaged from the notch D2. As no novelty is claimed for this clockmechanism, no detailed illustration or further description of thismechanism is deemed necessary.

On one side of the casing is a cylinder K, roc in which works a pistouJ, which is acted upon by a spring L in the lower part of said cylinder,thel tension of which spring serves to keep the piston'J normally at itshighest limit, but allowing -the 'same'to be depressed under tension ofthe spring when the device is sunken and acted u'pongby the, pressureof-v the water bearing upon the upper face of said piston.
